I've totally been on this Netflix anime kick lately. I friggin love the Seven Deadly Sins series. It wasn't too long ago when I binge watched both complete seasons.
Anyway, I didn't even know they were releasing a full length movie. Way too much shows to keep track of. This popped up on NF a few days ago and I finally got a chance to watch it today.
Pretty descent. It's only good if you are already familiar with the world and it's characters. Otherwise, newcomers will be completely lost.
I should really read the manga since I'm not too sure they are making another season.
